Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742506, here are decompositions:

7 + 8742499 = 8742506
13 + 8742493 = 8742506
37 + 8742469 = 8742506
43 + 8742463 = 8742506
127 + 8742379 = 8742506
139 + 8742367 = 8742506
193 + 8742313 = 8742506
313 + 8742193 = 8742506

Showing the first eight; more decompositions exist.
